ing and repairing leather belting for machin cry; and it consists incertain improvements in machines of this class, as hereinafter describedand claimed. 1

In the accompanying drawings, Figure 1 is a plan view of abelting-machine provided with my improvements. Fig. 2 is a side View ofthe same. Fig. 3 represents a section taken on line a: of Fig. 1. Fig.arepre'sents a section taken on line y y of Fig. 1. Fig. 5 is a planview of a punch-block. Fig. 6 is a plan showing certain details in thepunch-block and connections.

A designates a frame,to the inner and opposite sides of which aresecured the longitudim l racks a, underv which are the fixed longitudinal guides b for a sliding frame which carries a cutting-blade, ashereinafter mentioned.

13 indicates a table which has pivotal connections c with said frame andis adjustable in its inclination by means of a cam-shaft d, extendingunder the table and having bean ings in the frame. The shaft clmay beturned 1 nd fixed'in position by means of a lever d" on the extended endof the shaft and a red: 9, which is fixed to the frame. A corrugatedeccentric-roller f is journaled in the frame and provided with ahand-lever f, the purpose of said roller being to clamp the belting whenbeing out against a base-board c.

A sliding frame is formed of the uprights O, which areconnected bycr0ss-rods at the top and are provided with cleats at the bottom, whichextend into the guides 17. To the uprights O at their lower extremitiesis fastened a cutting-blade D, which extends across the table and is inposition to cut the leather belt ing on the table B with a shearing cut.

E indicates a roller, which extends across Serial No. 316,214. (Nomodel.)

the table B and is loosely connected by rods gwith theuprights C of thesliding frame, said roller being intended to rest on the belting infront of the blade D to keep the belting fiat against the table duringoperation.

F indicates an arm or additional frame, which is located at one side ofthe frame A and somewhat elevated, as shown. A headblock G is carried bythe arm F, and two 6c punches h and h. are mounted in the headblock,being passed through perforations in the same. The punch h is formed topunch holes in the belting :forrivets, and the punch 'h is adapted tostamp the rivets severally as they are passed into the holes made by thepunch h.

Within the head-block G. is also mounted a cross-form or T-shapedconnection on, which through a slot in the casing of the head-block, andby a spiral spring 8 on the lower stem of the cr0ss-form, which extendsthrough an aperture in the bottom of the head-block. Two vertical armsare carried by the crossform on, being pivoted thereto at h The saidarms is extend upward nearly to the top of the head block and downwardthrough openings in the bottom, as shown, the lower ends being providedwith jaws 1', extending 8o laterally therefrom an d being adapted tohold a rivet between them. From the jaws '5 extend two curved guides '11for the purpose hereinafter set forth. The upper ends ofthe arms is arebent toward each other and are connected by a spring 11 which tends topress them apart, and consequently to close the jaws v at the lower endsof said arms. Two screws 01 n are set in the top of the head-block inposition to impinge against the beveled surfaces on the upper ends ofthe arms lo when the latter are raised by the action of the spring 5- onthe crossform, the upper ends beingthus pressed together and the jaws ibe ing opened. 5 The punch h, which stamps the rivet, is in positionover a point between the jaws 2', where the rivet is held by said jaws,and both of the punches are sustained by springs 0, which raise themafter being driven downward. The head-bloc1r is provided with a handleg, by which it may be moved forward and is heldin position by a screw m,passed 70 v backward to bring the punches each to the right point to bedriven.

The face of the punch-block G (shown in plan in Fig. 5) is provided witha slot ,2, over which each of the punches is brought to be driven-one tomake the hole in the leather and the other to stamp the rivet. It isalso provided with a way for the slides '1' and 4*, which are placedtherein, and an aperture v for the passage of the burrs to be used withthe rivets, as hereinafter stated. A covering of sheet metal sis placedon the punch-block to keep certain parts in place, openingsbeing made inthe covering over the slot 2 and the aperture 11/.

The head-block G is connected by a rod '1) with apivoted lever I, to thelower end of which'is attached a rod 19, which is connected with a stockor stud r, projecting down from the notched slide 0", which moves in theface of the punch-block. An edged tool r is carried by a rod 19 which isloosely connected with'the rod p',the said tool 0" being held inposition with its edge in the slot 2 in the punch-block. The rod. 19 isprovided with an elbow p and an arm 19, as seen in Fig. 6, and is soconnected with p that when the latter is moved in either direction bythe movement of lever I a slight similar movement is imparted to thetool W. A rod or wiret is fixed in position within or under thepunch-block, the free end of the rod being turned up to the aperture '22in the block. On the rod t are placed the burrs t, which are to be setwith the rivets, the said burrs being pressed up through the aperture vagainst the plate 8 by a spring it, which is placed on the. rod. Theuppermost of the burrs is then in position to be pushed along by themovement of 'the slide 0", as hereinafter stated.

H indicates a pivoted arm, which extends over the head-block G and isprovided with a contact-surface 10 to rest on either of the punches h hwhen they are severally driven.

J indicates a striking-hammer, which is carried by a pivoted arm H,which extends over and is on the same vertical plane with the arm H. Ahook h is pivoted to the arm of the hammer J, and when the arms H H areboth raised the hook hconnects with a catch h on the arm H, and both ofsaid arms are thus held in the raised position shown in Fig. 2. One ofthe punches being then brought in position to be driven, the arm H ispulled downward, being thus released from the hook 722, and rests at 11.on the punch, when the hammer falls, striking the arm H and driving thpunch.

K indicates a magazine or inclined way for the rivets, which is formedof two parallel strips fixed in position adjacent to the frame F, therivets being placed with the heads to said frame, with the shanksbetween the parallel strips.

From the jaws i on the lower ends of the arms 7c extend two curvedguides 97., which are turned to the lower ends of the strips forming theinclined way K and are adapted to receive the rivets therefrom andconduct them to said jaws. The rivets are moved'one' at a time from themagazine K to the guides 'n by a pivoted notched block L, which is actuated by a tongue 10, which is made fast to the head-block G and movestherewith;

The sliding frame, which carries the cutting-blade D, is moved on theguides 19 by means of a shaft M,.provided with a crank and gearing N,carried by said frame, said gearing connecting with the racks a. v Thetable B is adjusted in its inclination by means of the cam-shaft (I, sothat as the frame which carries the cutting-blade moves forward adiagonal shearing cut is made through i the belting toward the edge ofthe table, Where the belting is out 01f, the end being thus formed for alap. The two. ends of the belt thus formed are placed one over'the'other. on the punch-block, and the hammer israised to its elevatedposition by means of the pivoted arm H, being retained in such positionby the hook it? The head-block G is then pushed back by meansof thehandle 9, bringingthe punch h to position over the slotv z in'thepunch-block, suchmovement actuatingfithe slide 0' through rods 19 '1)and pivoted lever I, and the said slide pushes the uppermost of theburrs 15' into position over the slot 2', so that the punch h whendriven willpass through the;

rolled down the said guides into its seat in the jaws 71 under thestamping-punch h. The head-block being then drawn forward brings thepunch 77/ and the rivet to position over the hole made in the leather bythe punch h,

such movement bringing the tool 'r by rods p p under the rivet, the edgeof said tool being in the slot .2. The punch h being then driven by thehammer, as before described, forces down the jaws and rivet, the latter.be ing driven through the hole in the leather and through the burr, andthe jaws, being spread apart by the punch as they strike the leather,are raised by the spring 3. The arms k, which carry the jaws '5, come incontact at their upper ends with the screws n n, by which the upper endsare moved toward each other sufficiently to open the jaws to receiveanother rivet. by contact with the edge of the tool r sufiiciently tohold the parts of the belt together, and after enough rivets have beenset in the manner described the belt is turned over and finished in theordinary way.

The slide 1', with the hole it, isused in com nection with the punch hwhen it is desired to punch out rivets from a belt to take the IIO endsapart. The head-block is moved to bring the punch h over the hole a, andthe belt is placed with the rivet under the punch, which is then struckwith a hammer. The slide 7' may be drawn out when it is desired to takeout the tool r 1.
